요약2 The bioelectrical impedance analysis (BI) has been proposed as a convenient, valid approach to estimate body composition in normal, healthy people. BI prediction equations are based on either population-specific or generalized models. The aim of this study was to develop a convenient, useful equation that would sufficiently predict fat-free mass (FFM) of Korean children. Subjects were 59 volunteers (M=38, F=21) aged 7-14 years X±SD (age=9.2±2.2 years, height=140.0±13.9 cm, weight=44.1±12.3 kg). Thus, in 59 children with different levels of body fatness, FFM based on dual-energy X-ray absorptiometry (DXA) was used as the criterion. To construct prediction equation for FFM, we used multiple regression analysis, whereby all possible combinations were examined. The linear multiple regression equation constructed for predicting the FFM was, for instance, FFM=?12.992+0.868*H2/ R+0.0161*R+0.338* age, where, H=body height (cm), R=right hand-left foot impedance (ohms). The results indicate that the above equation had the lowest SEE (1.24 kg). The FFM calculated using the new equation did not differ from that based on the UW method. In conclusion, the prediction equation in this study afford accurate and inexpensive means of estimating FFM in Korean children without having them remove their clothing.
